Poorly-chosen environments also apply a multiplier to actual application memory. Pointer-oriented languages as a rule give a 2x memory-size multiplier to everything, though higher is possible depending on how dynamic they are. I suspect that the DOM and JS runtimes add a significant multiplier to the UI memory cost.
